Without energy you cannot do a variety of things such as breed, explore, PVP and more!!
The basic way to obtain energy is to make sure your king is full!! (0% Hunger) which means every 15 minutes you will gain 10% energy! It takes two and a half hours to fully refill an empty energy bar all the way back up to 100%!

However there is ways you can refill your energy quicker! Such as:

Daily Boost!
Every Rollover you will get a free energy boost! It is recommended that you max out all your energy to 0% before using you boost!
Random Explore Encounters!
Very commonly as youre exploring you will come across both encounters and random texts granting you between 1-25% energy boosts. These can be both event and year-round encounters.
Gorilla Enclave Quests!
In the enclave, once you hand over a lion you have one of three options as a reward,energy, experience or impression, it differs depending on the difficulty you choose
The Lioness Quests!
As youre exploring you can come across an encounter which grants you a quest of claiming 50 lioness's, once you complete the quest a common reward is an energy boost, however they greatly vary

Levelling up King!
Once you reach fuil EXP you have the option to level up, once you do itll refill your energy all the way to 100! It is again, recommended that you max out all your energy to 0% before levelling up!
Personalities
Personalities such as Candid and Hyperactive both have energy increasing effects, Candid granting you + 3% extra energy with each successful lioness claim in explore. And hyperactive gains a button for +30% extra energy when your energy drops below 70% (however it is limited to one use per rollover)
